I think one thing that would be helpful to determine is what the point of this self-portrait is. Is it for a clear, well-lit standard headshot (actually what it sounds like you're going for?) If that's the case I would definitely stop down the aperture - as has been said already - because the shallow depth of field lends the whole thing a dreamy look that doesn't mesh well with that goal, or with the standard, "straight-ahead" pose and smile. I would also stand a bit farther away from the bounced light source, or try to soften it a bit - it's really intense.

If you're looking for something a little more dramatic, try turning so that the light is coming at an angle or from one side - the shadows will completely change the feel of the portrait, and the depth of field might be a bit more appropriate.
